The large number of communicatiin data of electric energy meter information acquistion causes the rising of communication link congestion.In order to realize the load balance of communication link and the safety of data transmission,the automatic control method of communication link congestion safety of electric energy meter information collection terminal is studied.The objective function of link congestion automatic control is constructed by taking the link bottleneck bandwidth,the link information transmission delay does not exceed the limit value,and the variance of the network resource occupancy rate and the link utilization rate is the least.The model is solved by the intrusion weed algorithm,and the link congestion automatic control scheme is output.On this basis,the conditional random field model is introduced to realize the secure transmission of energy meter information,and the secure automatic control of link congestion is completed.The experimental results show that the bottleneck bandwidth and link information transmission delay of the proposed method are less than the limit value,and the variance of network resource occupancy and link utilization is reduced.The proposed method can hide the original data characteristics of the energy meter information,and ensure the load balance and data transmission safety of the communication link.
